• D. 1 – Pulmonary vein; 2 – Inferior Vena cava; 3 – Pulmonary artery

Answer 1

The correct option is C 1 – Pulmonary artery; 2 – Superior Vena cava; 3 – Pulmonary vein

In the given diagram, ‘1’ represents the pulmonary artery that carries deoxygenated blood from the right ventricle to the lungs, while ‘2’ represents the superior vena cava that carries deoxygenated blood from the upper body parts to the right auricle. Further, ‘3’ represents the pulmonary vein that carries oxygenated blood from the lungs to the left auricle.
